Reference: EcoArt 2002
Description: This alliance consists of marshes dominated by ~Cladium mariscus ssp. jamaicense (= Cladium jamaicense)$. Occurrences of this alliance are sometimes very extensive, such as the Everglades of southern Florida and areas in the Bahamian Archipelago, though they can also occur in smaller patches. ~Cladium mariscus ssp. jamaicense$ is usually strongly dominant. Other species may include ~Pontederia cordata (= Pontederia cordata var. lancifolia), Sagittaria lancifolia, Eleocharis cellulosa, Proserpinaca palustris, Bacopa caroliniana, Bacopa monnieri, Ludwigia repens, Leptochloa fusca ssp. fascicularis (= Leptochloa fascicularis var. fascicularis)$, and ~Utricularia gibba (= Utricularia biflora)$. Algal periphyton consisting of cyanobacteria (blue-green algae) and green algae is often dense and well-developed, especially in sparser associations in the alliance. The algal periphyton breaks down the oolitic substrate and deposits biogenic marl. This alliance occurs in areas where the alkaline chemistry necessary for sawgrass is provided by underlying calcareous rock (oolite) rather than by brackish tidal influence [contrast V.A.5.N.n ~~Cladium mariscus ssp. jamaicense$ Tidal Herbaceous Alliance (A.1473)$$].
